During the study, 196 highly myopic eyes of 118 patients, who required at least 10 diopter correction to achieve 20/20 vision, were evaluated 10 years following the surgery. Uncorrected vision was 77% of best-corrected vision before the surgery procedure. Only 5% of eyes lost some quality of vision and 40% avoided the use of glasses. 61% of the eyes were within plus or minus 2 diopters after 10 years.
Lead investigator, Jorge Alio, claims that "This study has allowed us to demonstrate that, in spite of the prejudices about the limits of the LASIK technique, the results regarding predictability, efficacy and safety for high myopic patients are very good in the long term... This reference study, with a long time perspective, allows us to know the safety, precision and limits of LASIK in highly myopic eyes."
